95% 알루미나 세라믹스의 경도
95 alumina ceramic is an advanced industrial ceramic with alpha alumina (Al ₂ O ∝) as the main crystal phase and a content of up to 95%. It is made through fine powder preparation, molding, and high-temperature sintering processes. The high proportion of alumina content endows it with a series of outstanding physical and chemical properties, among which hardness is one of its most striking core characteristics.
What is the hardness of 95 alumina ceramics?
Hardness is a measure of a material’s ability to resist local indentation or scratching. For 95 alumina ceramics, we typically use Vickers hardness (HV) and Rockwell hardness (HRA) as objective measurements.
Vickers hardness (HV0.5): typically up to 1500-1650 HV
Rockwell hardness (HRA): typically up to 80-90 HRA
To provide you with a more intuitive understanding, we will compare it with some common materials:
Compared to quenched steel (approximately 600-800 HV), the hardness of 95 alumina ceramic is more than twice as high.
Compared to cemented carbide (YG6, approximately 1100 HV): the hardness is about 30% -50% higher.
Compared to ordinary glass (about 500 HV): its hardness is more than three times higher.
This extremely high hardness means that 95 alumina ceramics can effectively resist the scratching, wear, and indentation of the vast majority of abrasives and hard objects.
Product Application: The Application of Hardness
The extremely high hardness makes 95 alumina ceramics an ideal material for harsh environments, mainly used in:
- 내마모성 부품:
Sealing ring/mechanical seal: used for water pumps, chemical pumps, slurry pumps, etc. In media containing solid particles, its high hardness ensures extremely low wear rate and long service life.
Lining plate and lining brick: As the inner lining of ball mills, pipelines, and silos, it protects the metal body from material erosion.
Nozzle: Sandblasting and waterjet cutting nozzles can maintain stable aperture for a long time, ensuring machining accuracy. - Key wear-resistant parts:
Cutting tools and blades: used for cutting fiber materials in the textile and paper industries, with a lifespan far exceeding that of metal cutting tools.
Guide rails and slides: In automation equipment, provide high wear resistance and low friction moving surfaces. - Corrosion resistant environment:
Although hardness mainly resists mechanical wear, its inherent chemical inertness combined with high hardness makes it a dual functional component that is wear-resistant and corrosion-resistant in acidic and alkaline environments, such as chemical valves and pump components.
